Question

Solubility Curves Solute per 100 g of H2O (g) Temperature (°C) Using the Solubility graph above, answer the following questions carefully. 11. How does the solubility of HCl vary with the temperature of the water? 12. What is the solubility of NaNO3 (estimate carefully) at 30 °C - _____ at 55 °C - _ and at 75 °C - _______ 13. If 100 g of KNO3 was added to 100 g at H2O at 70 °C, would the resulting solution be saturated or unsaturated? 14. If a saturated solution of KCl in 100 g of H2O at 60 °C is cooled to 10 °C, approximately how many grams of the solute will precipitate out of the solution? 15. Which salt is the least soluble at 90 °C?
